HS Code for Sheet metal screws

Sheet metal screws are classified under HS code 7318.14 because they are threaded articles of iron or steel specifically designed to create their own mating thread in the material they are driven into. This classification is governed by the General Rules of Interpretation (GRI), specifically GRI 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Heading 7318 covers screws, bolts, nuts, and similar articles of iron or steel. Within this heading, the 7318.14 subheading is reserved for self-tapping screws. These screws are characterized by their hardened threads and sharp points, which allow them to penetrate and tap threads into sheet metal, plastics, or wood without the need for a pre-threaded hole. The material composition is a primary factor; as articles of iron or steel, they fall under Chapter 73. The functional design—the self-tapping feature—is the final determinant that separates them from standard machine screws or wood screws found in other subheadings of 7318.

Common Misclassification

Sheet metal screws are frequently confused with HS code 7318.15, which covers other screws and bolts, whether or not with their nuts or washers. The distinction lies in the self-tapping capability; 7318.15 is for screws intended for use with a nut or a pre-tapped hole. Another common error is 7318.12, which is specific to wood screws. While some sheet metal screws can be used in wood, their primary design for metal-tapping keeps them in 7318.14.
